Secret code fix - remove bground flag

There were two CLs that conflicted causing
the functionality to break again.  This CL removes
Intent.FLAG_RECEIVER_INCLUDE_BACKGROUND.  This is Ok
because the flag is in framework-sysconfig.xml.
ActivityManagerService.java ln:15772 checks for this flag and
then adds it.

Test: Brought up "Testing" activity using secret code
Test: Set (and then hit) breakpoint in ActivityManagerService.java
